Q: I am taking progesterone supplements and have no period, what is going on?

A: There are many possible reasons for not having your period:

• You are pregnant, or
• You did not ovulate, or
• You ovulated late, and your period will still come.

It's also possible that the progesterone prevents you from bleeding with or without ovulation. Stopping progesterone might make you bleed, but you should make sure first that you are not pregnant.
